200 V brushless motor controller

The MSK4324 is a 10 A, 200 V, three-phase MOSFET brushless motor controller with a convenient isolated baseplate package. This device has the normal features for protecting the bridge. Included is all the bridge drive circuitry, hall sensing circuitry, commutation circuitry and all the current sensing and analog circuitry necessary for closed loop current mode (torque) control. When PWM'ing, the transistors are modulated in locked anti-phase (complementary) mode for the tightest control and the most bandwidth. Provisions for applying different compensation schemes are included. The MSK4324 has good thermal conductivity of the MOSFET's due to a hermetic isolated package design that allows direct heat sinking of the device without insulators.
